Given numbers are 417,906,685,989
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 417,906,685,989 is 85315877310.
Find LCM of 417,906,685,989 with Prime Factorization
| 3 | 417, 906, 685, 989 |
| 139, 302, 685, 989 |
Multiply the prime numbers at the bottom and the left side.
3 x 139 x 302 x 685 x 989 = 85315877310
Therefore, the lowest common multiple of 417,906,685,989 is 85315877310.
LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
Firstly, we have to find the product of all the numbers.
417 x 906 x 685 x 989 = 255947631930
Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.
417 : 1, 3, 139, 417
906 : 1, 2, 3, 6, 151, 302, 453, 906
685 : 1, 5, 137, 685
989 : 1, 23, 43, 989
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 417,906,685,989, is 1.
Now, the common factors can be found like this.
417:3x 139
906:2x 3x 151
685:5x 137
989:23x 43
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3 = 3
Therefore, the value for common factors is 3.
Now that we have all the elements of the formula, we can plug them in to calculate the LCM.
LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
LCM = 255947631930/(1x3)
LCM = 255947631930/3
LCM = 85315877310
Thus, we can understand that the LCM of 417,906,685,989 is 85315877310.
